САЖЕТАК / ABSTRACT:
This paper focuses on the digital modeling of tunnels and underground engineering. Explore key technological breakthroughs from IFC to BIM. Firstly, the architecture of the IFC standard and its extension in the field of infrastructure (such as the IFC-Tunnel project) are introduced, and the IFC information model suitable for tunnel engineering is constructed by extending the component entities and establishing hierarchical associations. Secondly, the essence and implementation requirements of BIM are analyzed, and the idea of an online tunnel BIM platform based on WebGL is proposed, which is combined with GLTF format to solve the problems of inconsistent data format and difficult transmission of 3D model, so as to realize model lightweight and Web-side visualization. Finally, it is pointed out that the combination of IFC and BIM can promote the digitalization of tunnel construction, combine real-time simulation and advanced geological forecasting, improve decision-making efficiency and reduce construction risks, and provide a new path for tunnel engineering informatization.
